<p>
PHP is a general-purpose scripting language widely used to develop
web-based applications. It can run inside a web server using the mod_php
module or the CGI version of PHP, or can run stand-alone in a CLI.

<p>
Stefano Di Paola discovered two bugs in PHP. The first is a parse error in
php_variables.c that could allow a remote attacker to view the contents of
the target machine's memory. Additionally, an array processing error in the
SAPI_POST_HANDLER_FUNC() function inside rfc1867.c could lead to the
$_FILES array being overwritten.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could exploit the first vulnerability to view memory
contents. On a server with a script that provides file uploads, an attacker
could exploit the second vulnerability to upload files to an arbitrary
location. On systems where the HTTP server is allowed to write in a
HTTP-accessible location, this could lead to remote execution of arbitrary
commands with the rights of the HTTP server.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All PHP, mod_php and php-cgi users should upgrade to the latest stable
version:
</p>
<code>
# emerge sync
# emerge -pv ">=dev-php/php-4.3.9"
# emerge ">=dev-php/php-4.3.9"
# emerge -pv ">=dev-php/mod_php-4.3.9"
# emerge ">=dev-php/mod_php-4.3.9"
# emerge -pv ">=dev-php/php-cgi-4.3.9"
# emerge ">=dev-php/php-cgi-4.3.9"</code>
</resolution>
